The wife's father gathered to the market for foods, his wife as usual rewarded him with a list of "what to buy" where there was a bunch of medicines (to buy at the pharmacy) and at the end of the assignment "2 sells".
The test, so as not to fade, gave the list
to the pharmacist.
In short, he did not buy salad for dinner, but brought 2 bags of some herbs, it seems sweet... He says that the pharmacist had long guessed...
